My Thunderbird is set to use "Variable Width" font and "medium" size.
- When I write, it looks like "Noto Serif". OK.
- When I see my own post, the font is not what I sent out. It looks like some "san serif". And, also, size is not right.

So, how do you preserve font/fontsize in Thunderbird?

For example, some script that packages installed there for daily crons, and I need to change something. For example, an email address or so. There are even cases when I use cron for something that should be done another way, just because it is easy.

At work, we've migrated a bunch of startup stuff to systemd units. This eliminated a bunch of code we had before for lifecycle management, and generally made things easier. However, we're still just shipping cron files to /etc/cron.d/. That's easier to deal with -- plus it's simpler to simply stop the cron service during maintenance windows, rather than individual timers. Systemd timers do offer some features and advantages cron doesn't, but we don't require any of those features with our current scheduled jobs. If we were scheduling the running of a systemd unit, it would probably be worth switching to timers anyway. -- Chris Irwin email: chris at chrisirwin.ca xmpp: chris at chrisirwin.ca web: https://chrisirwin.ca From mb at 3nsoft.com Tue Jan 6 13:59:34 2026 From: mb at 3nsoft.com (Mikalai Birukou) Date: Tue, 06 Jan 2026 18:59:34 +0000 Subject: [kwlug-disc] Videos of January meeting Message-ID: <393a3054-82b8-458c-9cec-28a24f14a28a@3nsoft.com> All videos are here: https://archive.org/details/kwlug_meeting_2026-01-05 From cdfrey at foursquare.net Tue Jan 6 21:46:04 2026 From: cdfrey at foursquare.net (Chris Frey) Date: Tue, 6 Jan 2026 21:46:04 -0500 Subject: [kwlug-disc] systemd timer VS crontab In-Reply-To: <4d1fcd6f-c505-478c-aef0-f7f8e01824f0@yahoo.ca> References: <4d1fcd6f-c505-478c-aef0-f7f8e01824f0.ref@yahoo.ca> <4d1fcd6f-c505-478c-aef0-f7f8e01824f0@yahoo.ca> Message-ID: Still using cron, and occasionally even at/batch.

Like Chris, I still use cron. It's easy to update/maintain, especially if the editor is set. It also emails results (if I want) so I can debug/change with confidence. Systemd... doesn't cope well with non-dhcp nfs networks. It's meant for a laptop user in a cafe, perhaps? I munge /etc/network/interfaces, /etc/hosts, /etc/resolv.conf and turn off the resolved and time sync to make systems stable and predictable. It also does funky things with sockets that has had me wondering what's up with gpsd when it shouldn't touch gpsd. The binary journalctl means that figuring out what went wrong in boot is far more tedious than a simple grep over /var/log/*.log. I don't need the fancy pagination and process tree.

I can now hang out with all the cool kids. These are my observations: 1. BTRFS was excellent and defining choice, in hind sight. Snapshot makes backup so easy. I'm willing to take speed hit, but I found it's quite fast. BTRFS filesystem has "subvolume", eg. for CachyOS, - root is "@" subvolume, mounted at / - home is "@home" subvolume, mounted at /home So, - to back up /home within the current filesystem, just take snapshot. - to back up to another BTRFS filesystem, do "btrfs send | btrfs receive". I see 60MB/s throughput on my machine with SATA2 harddisks. 2. Font was surprising. Using same Firefox, same website, - Fedora has the best fonts. - CachyOS is close second. - OpenSUSE has the worst fonts. 3. CachyOS is the fastest. Fedora vs OpenSUSE felt about the same in speed. 4. Vim is Vim is Vim. It should be, but each distro has their own configuration stack. You have to watch out for that. I took me some time to get "indentation" that Slackware gives you by default. Conclusion: ----------- I'm satisfied with CachyOS, so far. I recommend people to try BTRFS distros. It will make your backup much easier. And, ability to do "rollback" is bonus. --William From chris at chrisirwin.ca Thu Jan 8 20:05:19 2026 From: chris at chrisirwin.ca (Chris Irwin) Date: Thu, 8 Jan 2026 20:05:19 -0500 Subject: [kwlug-disc] systemd timer VS crontab In-Reply-To: <5f265daf-bf19-4b23-b31e-453e220118c3@happydeys.ca> References: <4d1fcd6f-c505-478c-aef0-f7f8e01824f0.ref@yahoo.ca> <4d1fcd6f-c505-478c-aef0-f7f8e01824f0@yahoo.ca> <5f265daf-bf19-4b23-b31e-453e220118c3@happydeys.ca> Message-ID: On Tue, Jan 06, 2026 at 10:59:26PM -0500, Gordon Dey wrote: >Systemd... >doesn't cope well with non-dhcp nfs networks.

Do you have a link to any bug reports? I'm very curious how NFS breaks with static addresses, or how *disabling* time sync (presumany chrony?) is involved. Both Fedora and RHEL are still using NetworkManager by default, so I don't really have much experience with systemd-networkd. For resolv.conf, we've actually migrated our servers to use systemd-resolved (which isn't the default in RHEL) to resolve occasional issues with host lookups. One of the quirky issues being DNS1 undergoing maintenance, but DNS2 is still online. Sometimes programs will fail a DNS lookup, or won't repeat the request to the second DNS server. This problem is elimited with resolved. It's also the only viable system-level way you can decide to enforce DNSSEC, assuming your infrastructure is prepared for that. Unless you decide to implement another similar service like dnsmasq. FWIW, it's killer DNS feature is for machines on multiple networks, or with split-routing VPNs. It's intelligent enough to identify which network's DNS servers to send requests to, preventing DNS leakage in multi-route situations. >It also does funky things with sockets that has had me wondering >what's up with gpsd when it shouldn't touch gpsd. Probably just socket activation? Socket activation predates systemd by a few decades (inetd, xinetd, etc). However, it's become significantly easier with systemd, hence why more services are switching to it lately. That's generally a nice thing for some services to be fired up on demand, instead of always running. But sometimes you may not want that For example, gpsd probably takes time to get a lock, which may be a problem if you're using it as a time source, vs wanting to look at a map. You can probably do something like the following to simply start the service normally, instead of via socket: $ sudo systemctl disable gpsd.socket $ sudo systemctl enable --now gpsd.unit >The binary journalctl means that figuring out what went wrong in boot >is far more tedious than a simple grep over /var/log/*.log. I don't >need the fancy pagination and process tree. Just the log, thanks. I've found journalctl to be generally nicer than plain log files. We have multiple services that all log into journald (well, they just output to stdout, but systemd routes that to the journal automatically). If I'm troubleshooting an issue involving multiple services, I can do the following: journalctl -u service1.unit -u service2.unit Then I get can read through log output of both services together, rather than two windows with separate logs, and jumping around to line things up. One of my gripes is that apache httpd and samba still use their own log files. -- Chris Irwin email: chris at chrisirwin.ca xmpp: chris at chrisirwin.ca web: https://chrisirwin.ca From mb at 3nsoft.com Fri Jan 9 12:04:27 2026 From: mb at 3nsoft.com (Mikalai Birukou) Date: Fri, 09 Jan 2026 17:04:27 +0000 Subject: [kwlug-disc] From 39c3 - Rethinking of OS, Rust, security and memory moves between processes Message-ID: <87783047-89a1-460b-b998-e00881f30ec4@3nsoft.com> This almost skipped attention, and attention it deserves. https://media.ccc.de/v/39c3-xous-a-pure-rust-rethink-of-the-embedded-operating-system#t=855 From mb at 3nsoft.com Fri Jan 9 12:10:42 2026 From: mb at 3nsoft.com (Mikalai Birukou) Date: Fri, 09 Jan 2026 17:10:42 +0000 Subject: [kwlug-disc] From 39c3 - Rethinking of OS, Rust, security and memory moves between processes In-Reply-To: <87783047-89a1-460b-b998-e00881f30ec4@3nsoft.com> References: <87783047-89a1-460b-b998-e00881f30ec4@3nsoft.com> Message-ID: <36dd602d-6986-4c90-8581-f4c8a9e7c424@3nsoft.com> > This almost skipped attention, and attention it deserves. > > https://media.ccc.de/v/39c3-xous-a-pure-rust-rethink-of-the-embedded-operating-system#t=855 I wonder if this approach to memory will make micro kernels more desirable.

Replaces Postfix, Dovecot, OpenDKIM, fail-2-ban, Mailman (has a built-in mailing list, no need for the nightmare that is MM anymore), supports CalDAV, CardDAV, WebDAV, JMAP, IMAP, POP3, anti-spam, Sieve, etc. Web site's really fast, even the management console run from inside a Docker container is fast, well designed, well laid out. It's appealing to shed the 1,000+ options for Postfix, even more for Dovecot, plus all the ancillary tools required to run email. On the other hand, Postfix & Dovecot are what I know - and learned at great cost (time & frustration), and are where the jobs are. What brought me to this is, looking for a way to offer contacts & calendar syncing along with email hosting. NextCloud was my first choice, but trying to get the AIO (All In One) to support multiple domains in one instance is not well supported as best I can tell.

That's probably the best option. Eliminates feedback issues, best mic performance with least background noises, best audio quality for listening and can be repurposed for listening to music. I'd suggest considering an average or better quality setup for comfort & versatility. Earbuds seem to work well - I use cheap Bluetooth earbuds for phone calls & podcast listening. Not great for music though. Get someone to join a video conference with you to test audio quality during the return quality. Cameras are mostly useless, sometimes worse than useless - distracting and unpleasant. I have headset / mic combo for listening to music or participating in video conferences. I have a Bluetooth speaker if I'm just listening to a video conference. I have a camera / mic combo which I rarely / never use. Mic isn't bad but the headset's mic is better.

So perhaps, the decision would be based on : a) you have some noise locally and want to isolate that using a mic closer to your mouth b) better audio from other participants If you are in a quiet area and alone, then you may not need any external devices. I have not tried a separate camera, so can't comment on that. -------------- next part -------------- An HTML attachment was scrubbed...

The specific software really doesn't matter too much, as Zoom isn't implementing audio handling, that will be pipewire on a modern system. I used desktop speakers + laptop's built-in mic for a few years on Teams (still do, but was recently switched to Windows for work) >Background: >----------- > - I have lots of 3.5mm earphones/mic (from old phones) with single >combo plug.

If you like your 3.5mm headsets, you can get an adapter, just make sure you get the right direction: https://www.amazon.ca/Black-Splitter-Headphone-Microphone-Connector/dp/B071NDLCGC > - So, I bought $5 bluetooth speaker from Dollarama, which has >speaker and mic. Speaker works with CachyOS, but not mic. Bluetooth audio devices will usually have two profiles: A high-quality stereo output, and a low-quality mono output + mic input. With my bluetooth headphones on Gnome (on Fedora 43, if that matters), they are actually listed as two separate devices in sound settings: "Headphones" and "Handsfree". From experimentation in the past, they can not be used at the same time, and I remember the system not being able to switch if sound was in use. It was quite frustrating. However, whatever magic has happened since I last tested this years ago, it actually switched-over fairly gracefully when I just tested it. But it may require tweaking in your sound settings to set the preferred mic (the Mic shows up twice as well, but one doesn't actually work) That said, I wouldn't assume a $5 bluetooth speaker would provide a better experience than even a cheap wired headset. > - Maybe, all I need is USB "headset" (headphones + mic)? For simplicity sake, avoiding bluetooth will save you a bit of headache. But whether you want speakers + mic, headphones + mic, or a headset, this is really just a matter of preference. -- Chris Irwin email: chris at chrisirwin.ca xmpp: chris at chrisirwin.ca web: https://chrisirwin.ca From chris at chrisirwin.ca Mon Jan 12 21:48:57 2026 From: chris at chrisirwin.ca (Chris Irwin) Date: Mon, 12 Jan 2026 21:48:57 -0500 Subject: [kwlug-disc] Stalwart email server software: anyone know anything?

Always great to see JMAP support, even though I don't actually have a client that supports it yet.

Not sure if the AIO does more, but Nextcloud itself only provides DAV services, it doesn't provide mail hosting. There's a mail client app, but it expects a separately hosted IMAP server somewhere. It's alsy *very* barebones. NC's AIO supports running containers (I think, I don't use AIO), so maybe they've packaged something since. FWIW, I'm using Nextcloud for file sync, because it's the only option that hasn't regularly broken during upgrades (seafile), or required additional brain-power to remember how to access files on it (syncthing). But I'm not using it's CardDav/CalDav features at all. I may look at setting up stalwart to act as a backup for my mail/card/contacts, though. It's pretty interesting. -- Chris Irwin email: chris at chrisirwin.ca xmpp: chris at chrisirwin.ca web: https://chrisirwin.ca From ron at bclug.ca Wed Jan 14 05:00:49 2026 From: ron at bclug.ca (Ron) Date: Wed, 14 Jan 2026 02:00:49 -0800 Subject: [kwlug-disc] Stalwart email server software: anyone know anything?

The relayhost and mynetworks settings sure saved my butt recently, and I appreciate it. Got a new IP from VPS provider, it was blocked by Yahoo, so I had to relay via another server (that didn't even have proper rDNS set up, but Yahoo didn't care about that). Life saver until Yahoo unblocked me. I'm not sure that's possible with Stalwart, but it's too soon to say for sure. > Not sure if the AIO does more, but Nextcloud itself only provides > DAV services, it doesn't provide mail hosting. The AIO does not have email hosting. But it does have a lot of nice features like Nextcloud Office, and a working Whiteboard container out of the box.

It's pretty interesting. Indeed. I've been struggling to get Thunderbird to access the calendar I set up via `curl`, and the failed attempts gets my IP blocked so I can't even get back into the admin interface. Really, *really* been wasting time and pissing me off. There are settings for the config.toml file that are supposed to help with it, but I may be doing it wrong. Still, while I've given up temporarily, it still looks like Stalwart is a decent tool for WebDAV etc. services and lighter weight than full NextCloud.

I'm only hosting the individual Nextcloud container, and it's been fine. No office suite integration or anything. But I get where you're coming from.
